I've learned my way around Thera pretty well, although still learning a lot about strategies to fight various classes and what they're capable of (and their respective weakenesses). I've played a warrior, assassin, and shapeshifter thus far (in that order). Now looking to get serious with my RP and also to try a go at something a bit more complex.

Thinking about trying a drow conjurer or a duergar AP, but I am open to suggestions if you think these will be too tough for a newbie+. I haven't had much luck with PK so far so I'm looking for something that will be a strong PKer at the mid to high ranks (I'm fine with running/dying while young, which will be likely as a drow I realize). Leaning toward a mage of some sort. Although keep in mind I rarely have more than 1-2 hours at a time to play...

What do you think is the most fun without being incredibly challenging for a player that's still learning?

Assuming I go with a conjurer, any tips on what to do and not do, and general strategy, would be greatly appreciated. I have limited experience with cabals and their particular skillsets, so if there are advantages that are critical for a race/class combo I'd also love to hear any thoughts on that.
